The tissues release 250 mL of carbon dioxide into the blood in a minute…
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
The tissues release mL of carbon dioxide into the blood in a minute. Take per cent as bicarbonate, per cent as carbamino-haemoglobin and per cent dissolved in plasma.
- How much travels as bicarbonate?
- How much travels as carbamino-haemoglobin?
- How much travels dissolved?
Need a reminder? The key ideaShow
Carbon dioxide travels about per cent as bicarbonate, to per cent as carbamino-haemoglobin and about per cent dissolved. Carbonic anhydrase of the red blood cells makes go forward in the tissues and backward in the alveoli. Each mL of deoxygenated blood delivers about mL of carbon dioxide.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Total: mL. Shares: , and .
Plan. Take each share of the total.
Step 1. (a) mL.
Step 2. (b) mL.
Step 3. (c) mL.
Answer: mL, mL and mL.
Check. mL, the whole.
